Leveraging the standard library

The Kotlin standard library provides a wide variety of useful functions. With these functions, we can begin writing more functional code without having to reinvent the wheel. In this section, we'll explore some common functional patterns that can be achieved by leveraging the Kotlin standard library.

Manipulating collections
